I don't want to look at his age as a disadvantage against Caleb Plant, but it plays a big role knowing the latter is undefeated and almost 10 years younger. Experience wise he might have the advantage but Caleb's experience with 20 wins on which 12 is via knockout can't be denied as good too.
Looking at some website odds checker, we already know who's the favorite.
I can't consider this a walk in a park for Plant but he is in a good fight but definitely Plant will come out a winner here, he should come out with an impressive win here because he is after against Canelo Alvarez who is very impressive in his win against Smith, I believe he will make this a stepping stone for a match against Canelo, Canelo is the guy other boxers wants to meet right now.
